1.1.8 Avoid unintended Start.
While the adjustable frequency drive is connected to line power, the motor can be started/stopped using digital commands, bus
commands, references or via the Local Control Panel.
• Disconnect the adjustable frequency drive from line power whenever personal safety considerations make it necessary to avoid an unintended
start.
• To avoid an unintended start, always activate the [OFF] key before changing parameters.
• Unless terminal 37 is turned off, an electronic fault, temporary overload, a fault in the line power supply or lost motor connection may cause a
stopped motor to start.
1.1.9 Safe Stop of the Adjustable Frequency Drive
For versions equipped with a Safe Stop terminal 37 input, the adjustable frequency drive can perform the safety function
Safe Torque Off
(as defined by
draft CD IEC 61800-5-2) or
Stop Category 0
(as defined in EN 60204-1).
It is designed and deemed suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop. Prior to integrating and
using safe stop in an installation, a thorough risk analysis must be carried out on the installation in order to determine whether the safe stop functionality
and safety category are appropriate and sufficient. In order to install and use the safe stop function in accordance with the requirements of Safety Category
3 in EN 954-1, the related information and instructions of the

3.2.5 Safety Requirements for Mechanical Installation
Pay attention to the requirements that apply to integration and the field mounting kit. Follow the information in the list to avoid serious
damage or injury, especially when installing large units.
The adjustable frequency drive is cooled by air circulation.
To protect the unit from overheating, it must be ensured that the ambient temperature
does not exceed the maximum temperature stated for the
adjustable frequency drive
, and that the 24-hour average temperature
is not exceeded
. Locate the maximum temperature and 24-hour average in the
paragraph
Derating for Ambient Temperature
.
If the ambient temperature is in the range of 113°–131°F [45°–55°C], derating of the adjustable frequency drive will become relevant, see
Derating for
Ambient Temperature
.
The service life of the adjustable frequency drive is reduced if derating for ambient temperature is not taken into account.
3.2.6 Field Mounting

Overcurrent protection
Provide overload protection to avoid fire hazard due to overheating of the cables in the installation. Overcurrent protection must always be provided in
accordance with national regulations. The adjustable frequency drive is equipped with internal overcurrent protection that can be used for upstream
overload protection (UL applications excluded). See par. 4-18
Current Limit
in the
VLT HVAC Drive Programming Guide
. Fuses must be designed for
protection in a circuit capable of supplying a maximum of 100,000 A
rms
(symmetrical), 500 V/600 V maximum.
Non-UL compliance
If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in the table below, which will ensure compliance with EN50178.
In case of malfunction, not following the recommendation may result in unnecessary damage to the adjustable frequency drive.
